BACKGROUND

In the current Internet there exist many different types of media assetsin the form of digital files. Digital files may contain datarepresenting one or more types of content, including but not limited to,audio, images, and videos. For example, media assets include fileformats such as MPEG-1 Audio Layer 3 (“MP3”) for audio, JointPhotographic Experts Group (“JPEG”) for images, Motion Picture ExpertsGroup (“MPEG-2” and “MPEG-4”) for video, Adobe Flash for animations, andexecutable files.

Such media assets are currently created and edited using applicationsexecuting locally on a dedicated computer. For example, in the case ofdigital video, popular applications for creating and editing mediaassets include Apple's iMovie and FinalCut Pro and Microsoft'sMovieMaker. After creation and editing a media asset, one or more filesmay be transmitted to a computer (e.g., a server) located on adistributed network such as the Internet. The server may host the filesfor viewing by different users. Examples of companies operating suchservers are YouTube (http://youtube.com) and Google Video(http://video.google.com).

Presently, users must create and/or edit media assets on their clientcomputers before transmitting the media assets to a server. Many usersare therefore unable able to edit media assets from another clientwhere, for example, the user's client computer does not contain theappropriate application or media asset for editing. Moreover, editingapplications are typically designed for professional or high-endconsumer markets. Such applications do not address the needs of averageconsumers who lack dedicated computers with considerable processingpower and/or storage capacity.

Additionally, average consumers typically do not have the transmissionbandwidth necessary to transfer, share or access media assets that maybe widespread across a network. Increasingly, many media assets arestored on computer connected to the Internet. For example, services suchas Getty Images sell media assets (e.g., images) that are stored oncomputers connected to the Internet. Thus, when a user requests a mediaasset for manipulation or editing, the asset is typically transferred inits entirety over the network. Particularly in the case of digitalvideo, such transfers may consume tremendous processing and transmissionresources.

SUMMARY

DETAILED DESCRIPTION

FIG. 1 illustrates an embodiment of a system 100 for generating a mediaasset. In one embodiment, a system 100 is comprised of a master assetlibrary 102. In one embodiment, a master asset library 102 may be alogical grouping of data, including but not limited to high-resolutionand low-resolution media assets. In another embodiment, a master assetlibrary 102 may be a physical grouping of data, including but notlimited to high-resolution and low-resolution media assets. In anembodiment, a master asset library 102 may be comprised of one or moredatabases and reside on one or more servers. In one embodiment, masterasset library 102 may be comprised of a plurality of libraries,including public, private, and shared libraries. In one embodiment, amaster asset library 102 may be organized into a searchable library. Inanother embodiment, the one or more servers comprising master assetlibrary 102 may include connections to one or more storage devices forstoring digital files.

For purposes of this disclosure, the drawings associated with thisdisclosure, and the appended claims, the term “files” generally refersto a collection of information that is stored as a unit and that, amongother things, may be retrieved, modified, stored, deleted ortransferred. Storage devices may include, but are not limited to,volatile memory (e.g., RAM, DRAM), non-volatile memory (e.g., ROM,EPROM, flash memory), and devices such as hard disk drives and opticaldrives. Storage devices may store information redundantly. Storagedevices may also be connected in parallel, in a series, or in some otherconnection configuration. As set forth in the present embodiment, one ormore assets may reside within a master asset library 102.

For purposes of this disclosure, the drawings associated with thisdisclosure, and the appended claims, an “asset” refers to a logicalcollection of content that may be comprised within one or more files.For example, an asset may be comprised of a single file (e.g., an MPEGvideo file) that contains images (e.g., a still frame of video), audio,and video information. As another example, an asset may also may becomprised of a collection of files (e.g., JPEG image files) thatcollectively may be used to render an animation or video. As yet anotherexample, an asset may also comprise an executable file (e.g., anexecutable vector graphics file, such as an SWF file or an FLA file). Amaster asset library 102 may include many types of assets, including butnot limited to, video, images, animations, text, executable files, andaudio. In one embodiment, master asset library 102 may include one ormore high-resolution master assets. For the remainder of thisdisclosure, “master asset” will be disclosed as a digital filecontaining video content. One skilled in the art will recognize,however, that a master asset is not limited to containing videoinformation, and as set forth previously, a master asset may containmany types of information including but not limited to images, audio,text, executable files, and/or animations.

In one embodiment, a media asset may be stored in a master asset library102 so as to preserve the quality of the media asset. For example, inthe case of a media asset comprising video information, two importantaspects of video quality are spatial resolution and temporal resolution.Spatial resolution generally describes the clarity of lack of blurringin a displayed image, while temporal resolution generally describes thesmoothness of motion. Motion video, like film, consists of a certainnumber of frames per second to represent motion in the scene. Typically,the first step in digitizing video is to partition each frame into alarge number of picture elements, or pixels or pels for short. Thelarger the number of pixels, the higher the spatial resolution.Similarly, the more frames per second, the higher the temporalresolution.

In one embodiment, a media asset may be stored in a master asset library102 as a master asset that is not directly manipulated. For example, amedia asset may be preserved in a master asset library 102 in itsoriginal form, although it may still be used to create copies orderivative media assets (e.g., low-resolution assets). In oneembodiment, a media asset may also be stored in a master asset library102 with corresponding or associated assets. In one embodiment, a mediaasset stored in a master asset library 102 may be stored as multipleversions of the same media asset. For example, multiple versions of amedia asset stored in master asset library 102 may include anall-keyframe version that does not take advantage of intra-framesimilarities for compression purposes, and an optimized version thatdoes take advantage of intra-frame similarities. In one embodiment, theoriginal media asset may represent an all-keyframe version. In anotherembodiment, the original media asset may originally be in the form of anoptimized version or stored as an optimized version. One skilled in theart will recognize that media assets may take many forms within a masterasset library 102 that are within the scope of this disclosure.

In one embodiment, a system 100 is also comprised of an edit assetgenerator 104. In an embodiment, an edit asset generator 104 may becomprised of transcoding hardware and/or software that, among otherthings, may convert a media asset from one format into another format.For example, a transcoder may be used to convert an MPEG file into aQuicktime file. As another example, a transcoder may be used to converta JPEG file into a bitmap (e.g., *.BMP) file. As yet another example, atranscoder may standardize media asset formats into an Flash video file(*.FLV) format. In one embodiment, a transcoder may create more than oneversions of an original media asset. For example, upon receiving anoriginal media asset, a transcoder may convert the original media assetinto a high-resolution version and a low-resolution version. As anotherexample, a transcoder may convert an original media asset into one ormore files. In one embodiment, a transcoder may exist on a remotecomputing device. In another embodiment, a transcoder may exist on oneor more connected computers. In one embodiment, an edit asset generator104 may also be comprised of hardware and/or software for transferringand/or uploading media assets to one or more computers. In anotherembodiment, an edit asset generator 104 may be comprised of or connectedto hardware and/or software used to capture media assets from externalsources such as a digital camera.

In one embodiment, an edit asset generator 104 may generate alow-resolution version of a high-resolution media asset stored in amaster asset library 102. In another embodiment, an edit asset generator104 may transmit a low-resolution version of a media asset stored in amaster asset library 102, for example, by converting the media asset inreal-time and transmitting the media asset as a stream to a remotecomputing device. In another embodiment, an edit asset generator 104 maygenerate a low quality version of another media asset (e.g., a masterasset), such that the low quality version preserves while stillproviding sufficient data to enable a user to apply edits to the lowquality version.

In one embodiment, a system 100 may also be comprised of a specificationapplicator 106. In one embodiment, a specification applicator 106 may becomprised of one or more files or edit specifications that includeinstructions for editing and modifying a media asset (e.g., ahigh-resolution media asset). In one embodiment, a specificationapplicator 106 may include one or more edit specifications that comprisemodification instructions for a high-resolution media asset based uponedits made to a corresponding or associated low-resolution media asset.In one embodiment, a specification applicator 106 may store a pluralityof edit specifications in one or more libraries.

In one embodiment, a system 100 is also comprised of a master asseteditor 108 that may apply one or more edit specifications to a mediaasset. For example, a master asset editor 108 may apply an editspecification stored in a specification applicator 106 library to afirst high-resolution media asset and thereby creates anotherhigh-resolution media asset, e.g., a second high-resolution media asset.In one embodiment, a master asset editor 108 may apply an editspecification to a media asset in real-time. For example, a master asseteditor 108 may modify a media asset as the media asset is transmitted toanother location. In another embodiment, a master asset editor 108 mayapply an edit specification to a media asset in non-real-time. Forexample, a master asset editor 108 may apply edit specifications to amedia asset as part of a scheduled process. In one embodiment, a masterasset editor 108 may be used to minimize the necessity of transferringlarge media assets over a network. For example, by storing edits in anedit specification, a master asset editor 108 may transfer small datafiles across a network to effectuate manipulations made on a remotecomputing device to higher quality assets stored on one or more localcomputers (e.g., computers comprising a master asset library).

In another embodiment, a master asset editor 108 may be responsive tocommands from a remote computing device (e.g., clicking a “remix” buttonat a remote computing device may command the master asset editor 108 toapply an edit specification to a high-resolution media asset). Forexample, a master asset editor 108 may dynamically and/or interactivelyapply an edit specification to a media asset upon a user command issuingfrom a remote computing device. In one embodiment, a master asset editor108 may dynamically apply an edit specification to a high-resolution togenerate an edited high-resolution media asset for playback. In anotherembodiment, a master asset editor 108 may apply an edit specification toa media asset on a remote computing device and one or more computersconnected by a network (e.g., Internet 114). For example, bifurcatingthe application of an edit specification may minimize the size of theedited high-resolution asset prior to transferring it to a remotecomputing device for playback. In another embodiment, a master asseteditor 108 may apply an edit specification on a remote computing device,for example, to take advantage of vector-based processing that may beexecuted efficiently on a remote computing device at playtime.

In one embodiment, a system 100 is also comprised of an editor 110 thatmay reside on a remote computing device 112 that is connected to one ormore networked computers, such as the Internet 114. In one embodiment,an editor 110 may be comprised of software. For example, an editor 110may be a stand-alone program. As another example, an editor 110 may becomprised of one or more instructions that may be executed throughanother program such as an Internet 114 browser (e.g., MicrosoftInternet Explorer). In one embodiment, an editor 110 may be designedwith a user interface similar to other media-editing programs. In oneembodiment, an editor 110 may contain connections to a master assetlibrary 102, an edit asset library 104, a specification applicator 106and/or a master asset editor 108. In one embodiment, an editor 110 mayinclude pre-constructed or “default” edit specifications that may beapplied by a remote computing device to a media asset. In oneembodiment, an editor 110 may include a player program for displayingmedia assets and/or applying one or more instructions from an editspecification upon playback of a media asset. In another embodiment, aneditor 110 may be connected to a player program (e.g., a standaloneeditor may be connected to a browser).

FIG. 2 illustrates an embodiment of a system 200 for generating a mediaasset. In one embodiment, the system 200 comprises a high-resolutionmedia asset library 202. In one embodiment, the high-resolution mediaasset library 202 may be a shared library, a public library, and/or aprivate library. In one embodiment, the high-resolution media assetlibrary 202 may include at least one video file. In another embodiment,the high resolution media asset library 202 may include at least oneaudio file. In yet another embodiment, the high-resolution media assetlibrary 202 may include at least one reference to a media asset residingon a remote computing device 212. In one embodiment, the high-resolutionmedia asset library 202 may reside on a plurality of computing devices.

In one embodiment, the system 200 further comprises a low-resolutionmedia asset generator 204 that generates low-resolution media assetsfrom high-resolution media assets contained in the high-resolution mediaasset library. For example, as discussed above, a low-resolution mediaasset generator 204 may convert a high-resolution media asset to alow-resolution media asset.

In one embodiment, the system 200 further comprises a low-resolutionmedia asset editor 208 that transmits edits made to an associatedlow-resolution media asset to one or more computers via a network, suchas the Internet 214. In another embodiment, the low-resolution mediaasset editor 208 may reside on a computing device remote from the highresolution media asset editor, for example, remote computing device 212.In another embodiment, the low-resolution media asset editor 208 mayutilize a browser. For example, the low-resolution media asset editor208 may store low-resolution media assets in the cache of a browser.

In one embodiment, the system 200 may also comprise an image renderingdevice 210 that displays the associated low-resolution media asset. Inone embodiment, an image rendering device 210 resides on a computingdevice 212 remote from the high-resolution media asset editor 206. Inanother embodiment, an image rendering device 210 may utilize a browser.

In one embodiment, the system 200 further comprises a high-resolutionmedia asset editor 206 that applies edits to a high-resolution mediaasset based on edits made to an associated low-resolution media asset.

FIG. 3 illustrates an embodiment of a method 300 for editing alow-resolution media asset to generate a high-resolution edited mediaasset. In the method 300, a request to edit a first high-resolutionmedia is received from a requester in a requesting operation 302. In oneembodiment, the first high-resolution media asset may be comprised of aplurality of files and receiving a request to edit the firsthigh-resolution media asset in requesting operation 302 may furthercomprise receiving a request to edit at least one of the plurality offiles. In another embodiment, requesting operation 302 may furthercomprise receiving a request to edit at least one high-resolution audioor video file.

In the method 300, a low-resolution media asset based upon the firsthigh-resolution media asset is transmitted to a requestor in atransmitting operation 304. In one embodiment, transmitting operation304 may comprise transmitting at least one low-resolution audio or videofile. In another embodiment, transmitting operation 304 may furthercomprise converting at least one high-resolution audio or video fileassociated with a first high-resolution media asset from a first fileformat into at least one low-resolution audio or video file,respectively, having a second file format. For example, ahigh-resolution uncompressed audio file (e.g., a WAV file) may beconverted into a compressed audio file (e.g., an MP3 file). As anotherexample, a compressed file with a lesser compression ratio may beconverted into a file of the same format, but formatted with a greatercompression ratio.

The method 300 then comprises receiving from a requestor an editinstruction associated with a low-resolution media asset in receivingoperation 306. In one embodiment, receiving operation 306 may furthercomprise receiving an instruction to modify a video presentationproperty of at least one high-resolution video file. For example,modification of a video presentation property may include receiving aninstruction to modify an image aspect ratio, a spatial resolution value,a temporal resolution value, a bit rate value, or a compression value.In another embodiment, receiving operation 306 may further comprisereceiving an instruction to modify a timeline (e.g., sequence of frames)of at least one high-resolution video file.

The method 300 further comprises generating a second high-resolutionmedia asset based upon the first high-resolution media asset and theedit instruction associated with the low-resolution media asset in agenerating operation 308. In one embodiment of generating operation 308,an edit specification is applied to at least one high-resolution audioor video file comprising the first high-resolution media asset. In afurther embodiment, generating operation 308 generates at least onehigh-resolution audio or video file. In another embodiment, generatingoperation 308 further comprises the steps of: generating a copy of atleast one high-resolution audio or video file associated with a firsthigh-resolution media asset; applying the edit instruction,respectively, to the at least one high-resolution audio or video file;and saving the copy as a second high-resolution media asset.

In another embodiment of method 300, at least a portion of the secondhigh-resolution media asset may be transmitted to a remote computingdevice. In still yet another embodiment of method 300, at least aportion of the second high-resolution media asset may be displayed by animage rendering device. For example, the image rendering device may takethe form of a browser residing at a remote computing device.
